SPECIFICATION forming part of Letters Patent No. 651,317, dated June 5,1900.

Application filed January 16 1899. Serial No. 702,238. (No model.)

To all whom. it may concern.-

Be it known that I, OARL W. IVEISS, a citizen of the United States,residing in the city of New York, in the county and State of New York,have invented certain new and useful Improvements in Engines, of whichthe following is a specification, reference being had to theaccompanying drawings, forming a part hereof.

This invention is concerned with the feeding or delivery of thehydrocarbon or other fuel which forms the basis of the charge inexplosive-engines. I

The improvement is particularly applicable to multiple engines-that isto say, to machines having two or more engines coupledtogether, so thatthey shall work in synchronism, as when coupled directly to a commoncrankshaft-while the other feature of the invention referred to iscapable of a wider application and is not restricted to engines of thisparticular type. In multiple explosive-engines it is practicallyimpossible to provide independent feeding or feed-regulating devices forthe several cylinders which shall be perfectly synchronous in theiraction, the result being that a major portion of the work is performedby one engine and the highest possible efficiency is not attained.

The object of this invention is to provide a single feeding or afeed-regulating device (itbeing intended to include feed-governingmechanism as well as fuel-delivery mechanism) common to the severalsingle engines and having such an operativerelation therewith that thehydrocarbon or other fuel is delivered 0r admitted to each workingcylinder at the same relative point in its cycle as in the case of theother cylinder or cylinders, whereby each single engine performs itsproportion of the work and the maximum efficiency is attained. Themechanism in which the invention, as described hereinafter, is embodiedis free from complication, and in its operation effects the delivery ofthe hydrocarbon or other fuel into each working cylinder at the instantwhen the conditions Within that cylinder are favorable to itsintroduction. The character of the expanding fluid from which the pistonreceives its forward impulse is immaterial so far as concerns thatportion of the invention which relates to the exhaust; but all of thefeatures of the invention are illustrated in the accompanying drawingsand described hereinafter as embodied in a duplex explosive-engine of aWell-known type, in which oilis delivered to each working cylinder toform the basis of an explosive charge.

In the drawings, Figure 1 is aplan view of a duplex explosive'engine towhich the improvements are applied. Fig. 2 is a view, partly inelevation and partly in vertical central section, of one of the singleengines. Fig. 3 is a detail view in section of the fueldischarge nozzle.Fig. 4. is a detail view in section of the pump with its valves.

In the construction illustratedin the drawings there are two workingcylinders A, having each a piston B, connected by a pitman B with acommon crank-shaft 0, the latter having an electric generator O mountedthereon between the two single engines; but it will be obvious that agreater number of single engines'might be coupled together bya commoncrank-shaft or otherwise and that the force of the engine may betransformed into other forms of work than the development of electricalenergy. The devices for vaporizing the oiland for igniting the vapor maybe of any usual or suitable character and need not be described herein.

The device which regulates the delivery of the hydrocarbon or other fuelis shown as a cylinder g, which is connected with a supply vessel G andwith a delivery-orifice, as H, in each working cylinder. A plunger Gwithin the pum p-cylinder efiects the delivery and is operated as manytimes during the complete cycle of the multiple engine as there aresingle engines coupled together-that is to say, in the constructionrepresented in the drawings, in which two single engines are coupled tothe common crank-shaft one hundred and eighty degrees apart, the pump isoperated twice for each rotation of the crankshaft. Any suitablemechanical devices may be employedfor effecting the operation of thefeeding device as many times as maybe required. As represented in thedrawings,an

eccentric O is mounted on the crank-shaft,and its rod 0 is connected tothe middle joint of a pair of toggle-levers 0 One end of the pair ICO oftoggle-levers is pivoted at a fixed point, and the other is connected toone end of a bellcrank lever c. It will be seen that the forwardmovement of the eccentric-rod rocks the bell-crank lever, as does alsothe return movement, so that the bell-crank lever receives two movementsfor each rotation of the crank-shaft. A rod 0 is connected to the leverc and carries a flat-faced nut 0 which rests upon an incline 0 When theengine is running at normal speed, the end of the rod 0" strikes the endof a tongue f, which is operatively connected with the pump-plunger andactuates the same; but when the engine is running too fast the momentumof the rod and the nut as the latter travels up the incline will throwthe end of the rod above the end of the tongue and the plunger will beunaffected. A retarder may be carried by an arm extended from thebell-crank, as indicated at 0 to bear upon the rod 0 and prevent thesame from flying up too far when the engine is running very fast.

As before stated, the pump-cylinder is connected with the several singleengines and the efiective movement of the pump or other feed-regulatingdevices is so arranged in the particular construction shown as to takeplace as each engine-piston reaches the forward limit of its stroke, atwhich time the exhaustport a has been opened by the forward'movement ofthe piston B beyond it and the pressure in the engine-cylinder hasfallen practically to zero, so that there is no back pressure to resistthe flow of the oil, which is then delivered into the cylinder. At thesame instant the pressure in the other engine cylinder or cylinders issufficiently great to shut off the delivery of oil into the same. Itfollows, therefore, that the oil or other fuel is delivered only intothat cylinder which is in readiness to receive it and at theinstant whenit is required. Each engine receives the impulse of the exploding chargein turn and performs its share of the total work. The injection ordelivery of the fuel does not necessarily take place at the instant ofthe opening of the exhaust; but as the fuel follows from the regulatingdevice the path of least resistance both cylinders may be underpressure, though not under the same pressure.

The nature of the invention and the mode of operation of its severalfeatures will now be readily understood without further explanationherein. It will also be understood that the invention is not limited tothe precise construction and arrangement of parts shown and describedherein.

I claim as my-invention- 1. In a multiple-cylinder explosive-enginehaving several single engines coupled together, a single fuel-feedconnected to the several engines in common, means for operating saidfuel-feed once for each single ongine during a complete cycle of themultiplecylinder engine, and a governor to control the action of saidfeed, the charge at each operation of the feed being delivered to thatengine in which the pressure is lowest.

2. In a-multiple-cylinder explosive-engine having several single enginescoupled together, each of said single engines having an exhaust-port andmeans to open the same, a I

single fuel-feed connected to the several engines in common, means foroperating said fuel-feed as the exhaust-port of each single engine isopened, and a governor to control the action of said fuel-feed, thecharge at each operation of the feed being delivered to that engine inwhich the pressure is lowest.

3. In a multiple-cylinder explosive-engine having a common crank-shaftand several single engines coupled thereto at different points, a singlefuel-feed connected to the several engines in common, means foroperating said fuel-feed once for each single engine during eachcomplete rotation of said shaft, and a governor to control the action ofsaid feed.

4. In a multiple-cylinder explosive-engine having a common crank-shaftand several sin gle engines coupled thereto at different points, each ofsaid single engines having an exhaustport opened by the piston as itreaches the limit of its forward stroke, a single fuel-feed common tothe several engines, means for op erating said feed as the exhaust-portof each single engine is opened, and a governor to control the action ofsaid feed.
